Types

type ConfigFileHandler

type ConfigFileHandler struct {
	Config *config.Config

	RepositoryFactory RepositoryFactory

	CommandDirectoryOptions  []command_dir.CommandDirHandlerOption
	TemplateDirectoryOptions []template_dir.TemplateDirHandlerOption
	TemplateOptions          []template.TemplateHandlerOption

	// ConfigFileLocation is an optional path to the config file on disk in case it needs to be reloaded
	ConfigFileLocation string

	DevMode bool
	// contains filtered or unexported fields
}

ConfigFileHandler contains everything needed to serve a config file

func NewConfigFileHandler

func NewConfigFileHandler(
	config *config.Config,
	options ...ConfigFileHandlerOption,
) *ConfigFileHandler

NewConfigFileHandler creates a new config file handler. The actual handlers resulting from the config file are actually created in Serve.

It will use the options passed in using WithAppendCommandDirHandlerOptions and WithAppendTemplateDirHandlerOptions and pass them to the TemplateDir and CommandDir handlers.

TODO(manuel, 2023-06-20) This doesn't allow taking CommandDirOptions and TemplateDirOptions for individual routes.

Also see https://github.com/go-go-golems/parka/issues/51 to allow the individual config file entries to actually provide the options for the handlers.

In a way, the options passed here could be considered "defaults". The order of overrides would be interesting to figure out.

func (*ConfigFileHandler) Serve

func (cfh *ConfigFileHandler) Serve(server_ *server.Server) error

Serve serves the config file by registering all the routers.

To create the handlers, it will walk over each individual route and create the appropriate handler. For example, if the route contains a CommandDirectory, it will create a CommandDirHandler and register it with the server.

NOTE(manuel, 2023-06-20) Creating the handlers late, in the Serve method, is not ideal because it makes it hard for the creating function to override specific handler options if need be (also this could potentially better be handled by setting the right overrides and defaults in the config.Config object upfront).

func (*ConfigFileHandler) Watch

func (cfh *ConfigFileHandler) Watch(ctx context.Context) error

Watch watches the config for changes and updates the server accordingly. Because this will register / unregister routes, this will probably need to be handled at a level where we can restart the gin server altogether.

type ConfigFileHandlerOption

type ConfigFileHandlerOption func(*ConfigFileHandler)

func WithAppendCommandDirHandlerOptions

func WithAppendCommandDirHandlerOptions(options ...command_dir.CommandDirHandlerOption) ConfigFileHandlerOption

func WithAppendTemplateDirHandlerOptions

func WithAppendTemplateDirHandlerOptions(options ...template_dir.TemplateDirHandlerOption) ConfigFileHandlerOption

func WithAppendTemplateHandlerOptions

func WithAppendTemplateHandlerOptions(options ...template.TemplateHandlerOption) ConfigFileHandlerOption

func WithConfigFileLocation

func WithConfigFileLocation(location string) ConfigFileHandlerOption

func WithDevMode

func WithDevMode(devMode bool) ConfigFileHandlerOption

func WithRepositoryFactory

func WithRepositoryFactory(rf RepositoryFactory) ConfigFileHandlerOption

type ErrNoRepositoryFactory

type ErrNoRepositoryFactory struct{}

func (ErrNoRepositoryFactory) Error

func (e ErrNoRepositoryFactory) Error() string

type RepositoryFactory

type RepositoryFactory func(dirs []string) (*fs.Repository, error)

RepositoryFactory is a function that returns a repository given a list of directories. This is used to provision the CommandDir handlers.

func NewRepositoryFactoryFromLoaders

	commandLoader loaders.ReaderCommandLoader,
	fsLoader loaders.FSCommandLoader,
